At present, there is no unified definition and concept of special steel. It is generally believed that special steel refers to steel with special chemical composition (alloy), special process production, special organization and performance, and can meet special needs.
Special steel symbol
The symbols of special steel can also be called the brand, which is generally composed of three parts: Chinese pinyin letters, chemical element symbols and Arabic numerals.Among them, Chinese Pinyin often represents the product name, purpose, characteristics, or production process, while Arabic numerals mostly represent the percentage of chemical composition or the value of a certain performance.1. Carbon structural steel symbols consist of Q+digital+quality level symbol+deoxylona method symbol, such as Q235-AF, Q represents the first Chinese Pinyin first letter, Q235 indicates that the yield point is 235MPa, and the later AF represents A-level boiling steel.2. Carbon tool steel symbols are generally consisting of T+carbon content+chemical element symbol+A, such as T8MNA, which represents carbon tool steel number. Digital 8 represents the average carbon content of 0.8 ﹪, and MN represents more manganese -containing elements.A represents low phosphorus and sulfur content.
Special steel price
The first editors product is special steel produced by Xiamen Shuntiancheng Mold Steel Co., Ltd.. The name of this special steel is alloy tool steel. Its material is DAC. In additionSpecial steels of types can also be customized according to user needs.The price of this special steel is 88.00 yuan per kilogram. The product to be said in the second editor is special steel produced by Shanghai Baoyu Metal Products Co., Ltd.., The brands brand is CR5MO1V, but this product does not support processing customization, so customers who have special requirements for the size of the product should not choose special steel produced by this company. In addition, this special steel is a large number of wholesale products. Consumers buy it.The more special steel, the naturally cheaper its price. The specific price is 28.00 yuan per kilogram, and 10 kg is sold.
Special steel processing
Engineering structure alloy steel This refers to the alloy steel for engineering and building structure, including welding high -strength alloy structure steel, alloy steel steel, railways alloy steel, geological oil drilling alloy steel pressure vessels, alloy steel and high manganeseAbrasion -resistant steel and so on.This type of steel is used as engineering and building structures. In alloy steel, the total content of this type of steel alloy is low, but the high temperature alloy high temperature alloy of high temperature alloy is high.A heat -powered material for intensity, heat fatigue intensity, high temperature toughness and sufficient chemical stability, used for thermal components working at about 1000 ° C under high temperature conditions.
